Passing a socket id of "rte_socket_id()" can cause problems in non DPDK
applications as there is a dependency on the current logical core we are
running on.
Passing " rte_lcore_to_socket_id(rte_get_master_lcore())" as the socket id to
rte_memzone_reserve resolves these issues as the master lcore doesn't change.

Subject: [PATCH] lib/librte_ether: change socket_id passed to
rte_memzone_reserve
Change the socket id that is passed to rte_memzone_reserve from the socket id
of current logical core to the socket id of the master_lcore.
